With this first issue of 2021, I can report that our journal is moving closer to representing the global readership has made us most widely circulated scholarly museum in world. The ten papers and exhibition review demonstrate new advances practice are emerging on every continent. And, am now proud efforts build an editorial board reflects countries where readers live work have been successful....

The concept of entropy of a discrete fuzzy measure has been recently introduced in two different ways. A first definition was proposed by Marichal [10] in the aggregation framework, and a second one by Yager [25] in the framework of uncertain variables. We present a comparative study between these two proposals and point out their properties. We also propose a definition for the entropy of an o...

RFID technology is widely used in the fields of location and position awareness. The RFID data streams are uncertain and need accurate and timely processing, since they are influenced by many factors. We propose an uncertain data optimal algorithm for RFID data streams. By analyzing the existing deficiency in the conventional particle filter method, we use a method based on entropy to derive th...

This paper examines the impact of uncertain capital flows on growth to a group of 60 developing countries during the 1990s. We distinguish between total capital flows, official capital flows and private capital flows. For the three types of capital flows we derive a yearly uncertainty measure. We use the yearly uncertainty measures in ordinary least squares estimates, as well as system GMM esti...
